基于YIQ颜色空间的图像水印算法

本文给出一种彩色图像的数字水印算法,该算法基于YIQ颜色空间,应用了离散小波变换,利用随机种子选取了变换后子带的某些位置,嵌入了灰度标记。实验证明算法具有良好的性质,提取出的水印可证明其可靠性,对诸如噪声干扰等图像处理有良好的抗攻击性。

Image Watermarking Algorithm Based on YIQ Color Space

This paper presents a new watermarking algorithm devised for color images based on DWT in YIQ. it makes use of random seeds to embed gray watermarking .Experimental results demonstrate the validity of the approach and credibility of the extracted watermarking. this algorithm is robust to many image processing attacks such as Gaussian noise.
